"The West must encourage this process, but not just recklessly support everything that the party of war in Kiev does, closing their eyes to outrageous violations of human rights, outright lawlessness and war crimes. The efforts to lay the blame for the Ukrainian crisis on Russia are uNPRoductive."
The Ukrainian government has rejected direct negotiations with the rebels.
Ukrainian Prime Minister Arseniy Yatsenuk.
"This is the common position of the head of State and head of the government: the best and most effective format of negotiations is the Geneva format. Russia is trying to abandon this format by every means it can."
